The omni-grain color selecting machine is an important processing machine for the process of food sorting
There are two main sources of impurities in corn grain. On the one hand, it is due to the popularization of agricultural mechanization, and the corn is adulterated with corn and other impurities. On the other hand, corn is deteriorated because of storage, such as bad storage. This causes the quality of the raw material in the following processing, so when the corn is reprocessed, it is removed to ensure the quality of the raw materials. Maize selection has become an unavoidable process in grain processing, and the corn color selecting machine is the processing machine for the food sorting process. The birth of the corn color selecting machine can save a large amount of human resources and financial resources for the food sorting process, which will bring a lot of benefit to the grain processing enterprises. Maize separator is a light, machine, electric, pneumatic, which integrates high-tech integrated technology, is the realization of mechanization and automation of grain refining process essential food processing equipment.
Maize color selection is a process of screening of heterochromatic particles and impurities in maize using CCD optical imaging technology. After maize materials to processing site to determine the output of per unit time, the color of production and machine precision is inversely proportional to the output per unit time, the greater the color to choose the worse effect. In order to solve the problem of production and color selection, the color selection channel can be added to solve the problem. But adding color selected channel and can make the color separator fuselage for long, and sheet metal processing parts easy deformation under the condition of spent long, which brings the problems such as the mechanical structure is not stable. Therefore, this paper introduces a new type of mechanical structure. In corn raw grain impurity rate proportion of different color particles and impurities, the impurity in the corn material rate directly affect the maize color choose precision of the machine, the higher the rate of impurity color pick accuracy is lower, the worse effect. So, before starting work, according to the mix rate of maize material, yield and so on to set the color selection machine work mode and so on the relevant parameters. Parameter is set to end, the selected corn machinery through ascension into color separator into the hopper, corn right now from the hopper by vibration feeder for chute channel (namely choosing a color channel, its surface should be smooth without beating phenomenon) feed. The rice grain is arranged in the chute channel to set up the speed of the shaping of the plastic and the speed of the single layer and the uniform velocity of the corn flow to the area of the CCD camera.
